Show to premiere on Sept. 14

Jay-Z will perform “Run This Town,” off his new album “The Blueprint 3,” with Rihanna and West.

Other guests are forthcoming for the premiere.

Leno told reporters Wednesday that “The Jay Leno Show” will feature musical guests at least once or twice a week, but wouldn’t be a major part of the show (and unlike most late-night talk shows, won’t appear at the back end of an episode).

“Jay Leno” is also set to include a diet of celebs, regular segments and pre-taped pieces from correspondents.
